Cardio vascular system part 1

CARDIO-VASCULAR SYSTEMThe system which is related with the Heart & BloodCOMPONENTS OF CVS:- *Heart *Blood vessel -vein -artery -microcirculation/capillary


Components of the heart

COMPONENTS OF THE HEART:-

*Four chamber

-Left atrium

-Right atrium

-Left ventricle

-Right ventricle

* Superior vanecava (Attach with the Right atrium)

* Inferior vanecava (Attach with the Right atrium)

* Pulmonary vein (Attach with the left atrium)

* Pulmonary artery (Attach with the right ventricle)

* Aorta

* SA (Syno-atrial) node

*AV (Atrioventricular) valve

* Bi & Tri caspid valve

* Purkinjee fibre

* Three coverings

-Pericardium

-Myocardium (Cardiac muscle)

-Endocardium


Heart cardiac rate

HEART/CARDIAC RATE

`Heart rate is the number of heart beat per minute’

In fetus:140-160bpm

In children:120-140bpm

Adult:60-100bpm

Average:72bpm

#TACHYCARDIA

`When the heart rate is greater then 100bpm it is called Tachycardia’

Due to-

-Excessive water intake

-Mental hasitation

-Exercise

-Disease condition (fever, rheumatic fever, arthritis)


Bradycardia

#BRADYCARDIA

`When the heart rate is lower then 60bpm it is called Bradycardia’

Due to-

-Excessive water loss

-Tension

-Excessive rest

-Disease condition (Diarrhoea , vomiting)


Blood pressure

BLOOD PRESSURE

`Blood pressure is the lateral pressure exerted by the blood on per unit area of the blood vessel’

BLOOD PERUNIT AREA OF BV

BLOOD PRESSURE

NORMAL PRESSURE: 80-120mmHg


Types

TYPES:-

Mainly it has two types-

*Systolic pressure

*Diastolic pressure

*SYSTOLIC PRESSURE

`The pressure which is found by the ventricular systole’

Normal systolic pressure:120-140mmHg


Diastolic pressure

DIASTOLIC PRESSURE

`The pressure which is found by the ventricular diastole’

Normal diastolic pressure:70-90mmHg


Heart sound

HEART SOUND:-

The sound which is produced by the heart due to the vibration of the atrio-ventricular valve or intra cardiac blood flow’

HEART SOUND: LUB-DUB-LUB-DUB

TYPES:-

*First HS(S1)

*Second HS(S2)

*Third HS(S3)

*Fourth HS(S4)


Cardio vascular system part 1

*s1 due to closure of the AV valve*s2 due to closure of the semilunar valve*s3 due to first rapid filling phase*s4 is due to the second rapid filling phase

CAUSE OF HS
